I bought a Ruger Single Six new about a week and a half ago and the pistol has been pretty inaccurate to say the least talking all over a standard sheet of paper target at 25 yards not really grouping at all. I've tried CCI Blazers, Stingers, and Remington bulk pack all to the same results. It's the convertible with 6.5" barrel, and yes I've made sure I'm using the right cylinder. When I shoot .22 mag it groups well, talking about inch to inch and a half groups at 25 yards. My grandpa has a single six stainless and wood handled but convertible as well that I've shot and it has no problems with accuracy from the .22 long rifle. Is there a common break in period with these or do I have a dud? I'll try and post up some pics of the targets. Also it’s the adjustable sights and I've tried sighting in starting close and working out but once I hit about 15 yards the groups really open up with regular LR so I've just sighted it in with the .22 mags for the time being.
